Maths Tools for Quick Technical Calculations

From percentage breakdowns to number system conversions and descriptive statistics, SLR TECH maths tools give engineers, analysts, and students fast answers directly in the browser. The Percentage Calculator handles four common modes: finding a percentage of a value, calculating what percentage one number is of another, and computing percentage increases and decreases. The Number Base Converter translates between decimal, binary, hexadecimal, and octal — essential for working with low-level code, CPU registers, file permissions, and color values. The Statistics Calculator takes a list of numbers and outputs mean, median, mode, standard deviation, variance, min, max, and range in one pass.

All calculations happen locally in your browser. No data is sent to any server, making these tools suitable for sensitive engineering and research work.
